into said casing, a fuel valve therefor, constant connections wherebysaid fuel valve is opened by the opening of said air valve, a resilientmember for closing said fuel valve, and pivoted cam for limiting theopening of said air valve, for the purposedeserioed.

In vaporizer for hydrocarbons, the combination with a casing havinginlet and outlet openings, of an air valve for said inlet openingpivoted in said casing, a fuel-feed conduit opening into said casing, avalve in said conduit, an adjustable constant connection between saidvalves whereby the operation of said air vawe will operate said needlevalve, and a resilient member for returning said needle valve to itsseat.

6. In a vaporizer, the combination with a casing forming a mixingchamber and an air valve therein, of a fuel-feed conduit opening intosaid casing on the outlet side of said air valve, a needle valvecontrolling said conduit and having 11785176131 extending ad acent toseams collar adapted to be directl r engaged by said air valve, for thepurpose escribed.

7. in a vaporizer for hydrmcarbons, a pivoted air valve, a fuel feedregulating needle valve having its stem adjacent thereto, and aprojection on said air valve in constant cone llaCiljWltl] said stem forthe purpose described;

8. In a vaporizer for hydro-carbons, a riably opening air valve, havinga projec on one side thereof, and a fuel feed reguie needle valve havinga projection on its stem adjacent to the projection on said air vaive,and co-acting in contact therewith for the purpose described.
